I like the presentation of your channel, very nice I have a DIY channel of sorts as well, I make things from wood.

One thing I've found that helps my views a lot is using a site called http://www.instructables.com You post tutorials of what you make on there and you can add your YouTube video to the tutorial you make. This can get you a lot of views if they feature your instructable but either way you'll get extra views. So for your DIY videos I would try it!

I would like to point out that I'm not paid by instructables! haha, I just find it to be very useful so I thought I'd let you know.
